https://issues.apache.org/jira/browse/IMPALA-14955 When an HDFS/libhdfs operation fails, Impala currently includes libhdfs root cause output in `GetHdfsErrorMsg()`. However, some failures, especially exceptions raised inside filesystem client code, need the full Java stack trace to identify the actual failing path. This change appends `hdfsGetLastExceptionStackTrace()` to the HDFS error message when libhdfs provides one. ## Motivation We hit an issue earlier due to using Ozone (HCFS): ``` Failed to close HDFS file Error(255): Unknown error 255 Root cause: ArrayIndexOutOfBoundsException ``` but the actual Java stack trace was not captured in the query/profile error. Including the libhdfs stack trace would be help immensely. -- This is an automated message from the Apache Git Service.
